I found out yesterday that I've gotten picked up for grad school! I'm tentatively going to be working on nano-sensors for UMCP's aerospace engineering smart structures lab. I have yet to read any of the background material, but it'll basically be tiny "fingers" of metal which behave similar to quartz crystals... you deflect them and they create a voltage. If you have arrays of them, oriented in different directions, you can detect accelerations, fluid flows, etc. It's not entirely what I was shooting for, but it's really cool, nonetheless!
